To .rqffi HEY/ 0111 {It tutti "concern:

Be it known that-I, EDWIN-NORTON, of'the city, county, and Statefofi NewYork, have invented or discovered new and useful 1mproveinents in Mills.for Rollin'g'Sheet Metal,

of which thefollowing is a specification.

to another, Usually the inspection is made whilegthe sheetsare travelingflat-wise just as which the sheets. are fed into and from therolls 13and 14. 1

they :issue from therolls, so that only one slde of each sheet isinspected, or if bothsides are to be inspected :eachsheet mustbereversed by hand." pr'acticeis manifestly inefficient In the cold'snngelaa'a nert the pass through several stands of rolls the same' endforemost themolecules of the metalbe f iron of an inferior quality.

By my present come strained or displaced, so-as to produce inventionthe:metal islcold' rolled and reversed end for en d between'suc- 'cessivestands ofrolls, permitting not only 'an inspection of the metal,- butalso securing a uniform and superior'article.

. ,I provide for the feeding of'the metal "into" :and' through the rollsbygravity. Thisfeature is valuable even Where the reversingme'chanism'jis omitted, as it saves feeding the;cost=of repairsvandoperatingthe same.

- My invention'is designed with special reference to finishing metalplatespreparatory to the pickling and tinning operations, though it isby no means to be confined to this purpose, as it may haveluse asidefrom a finish ing-Inilln I M I Referring to the drawings. whichaccompany this specification and constitute 'a partthereof, Figure 1is-aside elevation of my inclinedrolling-mill, and Fig. 2 is 'a viewfrom above looking at right angles to the :roll- -passes. v

In'the drawings,- 1 represents a pair-of rollhousings slidable on theshoes 2 in the usual manner.

The housings are inclined about forty-five degrees in the direction ofthe line of feed, which isindicjated by the arrow'3;

' the housings 1.

Sand "9 represent tables or chutes on which'the sheets are fed into andfrom the rolls 4 and 5.

t ,Seated on the shoes 10 is a second pair of My invntionfrelates; tomills for rolling sheet metal, and particularly to thatclass of millsWhere-an inspection of the sheets is re; quiredas they are fed from onestand-jot rolls housings 11,, inclined in the same direction as In theinclined openings 12 (one only being shown) in the housings 11 are therolls 13 and 14, adjustable by means of the screws 15.

16 and.17 represent the tables or chutes on The housings 11 are placedat a lower level than the housings 1 in order that the line of feedthrough the rolls 13 and 14 may be substantially in line with the lineof feed of the rolls 4 and 5'. The exact relation of the two sets ofhousings 1 and 11 is not necessarily as shown, as my invention is not tobe limited to any definite difference between the levels of the rolls.Indeed in its broadest conception they may be on the same level. 1" Journaled between the two setsof housing's 1 and 11' is the rotatablemagazine or carrier 18, journaled in the projections 19 at the rear ofthe housings 1.

The carrier conslsts, preferably, of a shaft having spaced about itsperiphery a plurality of rows of fingers arr'an ed like the s okes ofseveral wheels in axial a inement. T e o enings or s aces betweenadjacent longitu inal rows of ngers or s okes constitute pockets 20,'into which the s sets are fed from rolls 4 and 5' The corner is rotatedintermittently by anysuitable mechanism readily devised by anordinarily-skilled mechanic, so as to place one "of the pockets 20 inposition to receive a sheet as it issues from the rolls 4 and 5 and torotate the'same in the direction of the arrow 21in time to bring thenext lower pocket into position to r'eceivethe next sheet as it veys thesheets step by ste as described,

until they have accomplishe substantially a half-revolution, when theyslide out of their .pockets upon table 16 and into the pass of the rolls13 and 14. The arrow 22 indicates the direction the sheets takeafterleaving the last-named rolls.

An inspector has his position at the end of the carrier and examinesonesurface of the sheet as it lies on the entering side of the carcomesfrom'the said rolls. The carrier con- I am .enabled to keep in motionfrom one' stand of rolls to another possibly not over five or six feettherefrom a large number of sheets, and this. as fast as the rolls canfeed them. The sheets are fed automatically by gravity from the table 8through both sets of rolls and over the carrier, leaving the inspectorto devote his .wholentime to the insipection and the Withdrawal orreversal of efective sheets.

. Ifthe roll-passes were at the same level,

the sheets would have to be fed to and from therolls and to and from thema azine or carrier by hand or some mechanica devices. This feature ofmy invention has utility alone Where it is desired to feed metal in anyform from one stand of rollsto another, as is evident.

My invention is susc'e tible of many modifications, and Ido not esirethe same to be tary carrier between the said sets of rolls at i anintermediate level, the levels being such that the higher set of rollsfeeds the work by ravity into said carrier and said carrier eeds thework-by gravity to the rolls of the lower set. 7
